备用:
在调试一个前后端分离的项目,发现登录成功后已经把信息保存到session中了,再从session中取得当前用户信息的时候发现取不到,debug发现sessionId已经变了,自己网上查了很多资料,并不准确,
把自己的解决分享给大家:
后端拦截器:
//拦截器添加跨域支持(如果是web.xml配置拦截器,请将@component删除) //@Component public class CORSFilter implements Filter { @Override public void init(FilterConfig filterConfig) throws ServletException { } @Override public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) servletRequest; HttpServletResponse response = (HttpServletResponse) servletResponse; response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin")); response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE"); response.setHeader("Access-Control-Max-Age", "3600"); response.setHeader("Access-Control-Allow-Headers", "x-requested-with"); response.setHeader("Access-Control-Allow-Credentials","true"); //是否支持cookie跨域 filterChain.doFilter(servletRequest, servletResponse); } @Override public void destroy() { } }
关键点:
response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin"));
response.setHeader("Access-Control-Allow-Credentials","true"); //是否支持cookie跨域
前段代码:
request: function(param) { var _this = this; $.ajax({ xhrFields: { withCredentials: true }, type: param.method || ‘get‘, url: param.url || ‘‘, dataType: param.type || ‘json‘, data: param.data || ‘‘, success: function(res) { console.log("网络请求结果:"+res.toString()); //请求成功 }, error: function(err) { typeof param.error === ‘function‘ && param.error(err.statusText); } }); },
关键点:
在ajax请求中增加
xhrFields: {
withCredentials: true
},
